Embodiment Construction

[0027] The present invention is described in detail below in conjunction with accompanying drawing.

[0028] A method for feeding rigid dummy rods for vertical continuous casting, comprising the following steps:

[0029] refer to figure 1 , step 1, in the casting preparation mode, the rigid dummy bar 2 is placed on the billet roller table 3 by the workshop crane 1, the billet roller table 3 runs counterclockwise, and the two billet pinch vertical rollers 4 run simultaneously, and the The rigid dummy rod 2 is sent into the blank receiving trolley 6 which is waiting horizontally;

[0030] The arrangement of the two slab pinch vertical rollers 4 is convenient for the rigid dummy bar 2 to accurately enter the slab receiving trolley 6, and is also suitable for continuous casting machine short-length billet discharge.

[0031] refer to figure 2 , step 2, the reel of hoisting device 5 rotates clockwise, so that the blank receiving trolley 6 loaded with rigid dummy bar 2 is inclin...

Abstract

The invention discloses a method for sending vertical continuous casting rigid dummy bars upwards. Under a casting preparing mode, the rigid dummy bars are placed on a blank outlet roller table through a workshop crane and are sent into a horizontal waiting blank receiving trolley; a coiling block of a winding plant runs clockwise, and the blank receiving trolley is pulled by a steel rope to obliquely enter a fixed oblique rail; the winding plant runs clockwise to enable the blank receiving trolley to enter a swinging track; the winding plant stops running and carries the blank receiving trolley and the rigid dummy bars to swing anticlockwise to a vertical position; a hydraulic electromagnetic positioning mechanism acts simultaneously to push and pull the rigid dummy bars to a stand state; the coiling block of the winding device runs anticlockwise, the rigid dummy bars are sent upwards to a crystallizer under the successive relay running of a plurality of sector-shaped driving rollers with the hydraulic cylinder clamping function and are clamped by the three sector-shaped driving rollers at the topmost part to keep static, and then the dummy bars are sent upwards. The method solves the problem of loading of the continuous casting rigid dummy bars, is safer and has higher maneuverability.

Description

technical field [0001] The invention relates to the technical field of continuous casting in the metallurgical industry, in particular to a method for feeding rigid dummy rods for vertical continuous casting, which is suitable for loading dummy rods for vertical slab continuous casting with an ultra-thickness of 500mm and above question. Background technique [0002] At present, the thickest slab continuous casting machine in the world is 450mm (5# continuous casting machine of Dillingen Steel Works, Germany), and no slab continuous casting machine with a thickness of more than 500mm has been put into production. [0003] For ultra-thick (such as 500mm and above) slab continuous casting, a vertical model is required due to the casting process and cost-effectiveness of investment, and it is difficult to realize the delivery of the dummy car due to the limitation of the bending radius of the flexible dummy bar with large thickness , so it is necessary to use a rigid dummy bar...
